D. Is the data skewed? If so, is it skewed right or skewed left? (Answer Left or Right or Not Skewed)

Answer 1

a.) mode b.) 36 c.) yes d.) skewed left

Answer 2

Data set = 12,14,28,28,30,30,32,32,32,32,34,34,34,36,36,36,36,36,38,38

A.) Median

B.) Median = 33

C.) Yes, Outliers: 12 and 14

D.) Skewed left

Explanation:

Outliers: Points in the data set that are either way too small or way too big than other numbers in the data set.

Skewed: A sudden change in the data set going away from the data set:

Skewed right: If most of the data are on the left side of the histogram but a few larger values are on the right, the data are said to be skewed to the right.

Skewed left: If most of the data are on the right, with a few smaller values showing up on the left side of the histogram, the data are skewed to the left.

Not Skewed: If the data are symmetric, they have about the same shape on either side of the middle.

Hope this helps!
